Trigonometry is the branch of mathematics that deals with the understanding of the relationship between various properties of a triangle. Trigonometry has found its application in the field ranging from Engineering to Art and Architecture to Astronomy. In this chapter, we will learn about some Applications of Trigonometry. Let’s start.

**FAQs on Some Applications of Trigonometry**

**Question 1: What is the application of trigonometry in real life?**

**Answer:** There are many uses of trigonometry such as to roof a house, to make roof inclined (in case of single individual bungalows) and the height of the roof in a building, etc. In addition, the aviation and naval industry use it. Moreover, cartographers use it in creating maps and it has applications in satellite systems.

**Question 2: What is the importance of trigonometry? **

**Answer: **Simply we use it for the study of triangles and the length and angles of their sides. Also, it is one of the most important fields of mathematics, especially for careers that are built around calculating angles. Besides, the working knowledge of trigonometry and its uses is important for students of all ages.

**Question 3: What are the six function of trigonometry?**

**Answer:** The six function of trigonometry are sine (sin), cosine (cos), Tangent (tan), cosecant (cosec), secant (sec), and cotangent (cot). Besides, these are also trigonometric ratios and they have a relationship with each other.

**Question 4: What are the branches of trigonometry?**

**Answer:** Trigonometry has two branches:

**Plane Trigonometry:**It deals with the relationship between angles and sides of triangles located on a plane surface.**Spherical Trigonometry:**It studies the curved triangles drawn on the surface of a sphere.
